"As an omnivore I feel compelled to eat meat, dairy, grain, vegetables with no bias."
As an omnivore, you were designed and programmed to consume dairy only until you were weaned, and then you lose most of the ability to digest it. As well as the ability to procure it, in the natural environment.
It wasn't until the artificial environment of shpeherds and all came around that dairy became a food group again, so it certainly isn't in your programming genetically.

As for why some tribes think termites are yummy while most of us just abhor bugs...except maybe crabs and lobsters....no accounting for taste, is there?
